The River Clyde (Scottish Gaelic: Abhainn Chluaidh, pronounced [ˈavɪɲ ˈxl̪ˠuəj]) is a river that flows into the Firth of Clyde, in the west of Scotland. It is the eighth-longest river in the United Kingdom, and the second longest in Scotland after the River Tay. It runs through the city of Glasgow. The River Clyde estuary has an upper tidal limit located at the tidal weir next to Glasgow Green.
Historically, it was important to the British Empire because of its role in shipbuilding and trade. To the Romans, it was Clota, and in the early medieval Cumbric language, it was known as Clud or Clut. It was central to the Kingdom of Strathclyde (Teyrnas Ystrad Clut).
